|Abstract||Some species of Armillaria are among the most important root disease pathogens of broad-leaved trees, while other Armillaria species behave as saprophytic fungi. In Europe, at least six species are reported : A. borealis, A. cepistipes, A. gallica, A. mellea, A. ostoyae and A. tabescens. According to Guillaumin et al. (1985)1, A. ostoyae and A. mellea are considered as primary parasites able to infest healthy trees while the other species are considered as weakness parasites on stressed trees and behave as saprophytes on dead wood. In order to evaluate the importance and the diversity of those fungi along the watercourses in Wallonia, samples (rhizomorphs, mycelium and fruiting bodies) were collected from the main riparian tree species and analysed by PCR-RFLP.|
